摘　　要：利用全二维气相色谱-质谱联用技术对木兰科含笑属福建含笑、醉香含笑、深山含笑、乐昌含笑、野含笑5种木材丙酮抽提液的化学成分进行测定分析,探明含笑属5种木材丙酮抽提液的主要化学成分;并结合生长速率之含毒介质培养法分析丙酮抽提液对含笑属5种木材腐朽菌的抑制作用。结果表明,福建含笑、醉香含笑、深山含笑、乐昌含笑、野含笑5种木材丙酮抽提液的主要成分分别有17、23、27、27和26种。福建含笑、醉香含笑和乐昌含笑木材丙酮抽提液中含量最高的成分分别是肌醇、木香烃内酯和氰乙酸乙酯,含量分别为57.98%、25.97%和15.63%;深山含笑和野含笑木材丙酮抽提液中含量最高的成分均为冰乙酸,含量分别为24.89%和23.64%;福建含笑木材丙酮抽提液中特征成分为α-香附酮、α-愈创木烯、9-氧杂壬酸;醉香含笑丙酮抽提液中特征成分为α-卡地诺和2-(4-羟苯基)乙醇;深山含笑丙酮抽提液中特征成分为赫曲菌素;乐昌含笑丙酮抽提液中特征成分为2-propyl-2,3-dihydropyran-6-one和惕各酸香茅酯;野含笑丙酮抽提液中特征成分是Dihydro-3-methylene-5-methyl-2-furanone和6,7-二甲氧基异喹啉;含笑属5种木材丙酮抽提液对彩绒革盖菌和密黏褶菌均有不同程度的抑制作用,且抑菌效果随其浓度增加而提高。The chemical constituents of the acetone extracts from five species of wood such as Michelia fukianensis,M.macclurei,M.maudiae,M.chapensis and M.skinneriana wood in Michelia genus of Magnoliaceae family were determined by full two-dimensional gas chromatography-mass spectrometry in order to explore the main components of acetone extracts from five species of wood and their differences and the inhibitory effects of acetone extracts on five species of white rot fungi were analyzed by the method of toxic medium culture with growth rate.The results showed that there were 17,23,27,27 and 26 main components of acetone extracts from M.fukianensis,M.macclurei,M.maudiae,M.chapensis and M.skinneriana wood respectively.The most abundant components of acetone extract from M.fujianensis,M.macclurei and M.chapensis wood were inositol,lignans and ethyl cyanoacetate,respectively,accounting for 57.98%,25.97%and 15.63%,respectively.The most abundant component of acetone extract from M.maudiae and M.skinneriana wood was glacial acetic acid,accounting for 24.89%and 23.64%,respectively.The characteristic components of acetone extract from M.fujianensis wood wereα-cyperone,α-guaiacene and 9-oxazanoic acid;the characteristic components of acetone extract from M.macclurei wood wereα-cardinol and 2-(4-hydroxyphenyl)ethanol,the characteristic components of the acetone extract from M.maudiae wood was 8-hydroxy-3-methyl-isochroman-1-one;the characteristic component in acetone extract of M.mirifica was 2-propyl-2,3-dihydropyran-6-one and citronellyl tiglate,the characteristic components of acetone extract from M.skinneriana wood were Dihydro-3-methylene-5-methyl-2-furanone and 6,7-dimethoxyisoquinoline.The acetone extracts from five species of wood in Michelia genus had different inhibitory effects on Coriolus versicolor and Gloeophyllum trabeum,the inhibitory effect increases with their concentration.
